1 TCFP HazMat Operations Test Questions and Answers 202 4 When responding to hazardous materials/WMD incidents Operations level responders shall be able to preform the following task... - Correct Answer -1. Analyze a HazMat incident to determine the scope of the problem 2. Plan an initial response 3. Implement a planned response 4. Evaluate the progress Analyzing a hazardous material incident to determine the scope of the problem involves... - Correct Answer -1. Surveying the incident to identify containers and materials involved, determine if wether hazardous material has been released and evaluate the su rrounding conditions 2. Collect hazard and response information from SDS, CHEMTREC and shipping/manufacturer contracts 3.Predict the behavior of Hazardous materials and its container 4.Estimate the potential harm through TRACE -MP What does TRACE -MP stand for? - Correct Answer -Types of potential harm at Hazardous Material/WMD incidents. Thermal Radiation Asphyxiation Chemical Etiological Mechanical Psychological/ Psychogenic The initial response at a HazMat incident is determined by.. - Correct Answer -The capabilities and competencies of available personnel and personal protective equipment The response objectives at a hazardous material/WMD incident include... - Correct Answer -1.Evacuation 2. Search and Rescue 3. Exposure protection/ Isolating the Area 4. Defensive control techniques 5. Crime scene management and evidence preservation 6. Recovery and termination Describe the response options available for Evacuation - Correct Answer -1. Full scale evacuation 2. Shelter -in-place 3. Combination 2 Describe the response options available for Search and Rescue - Correct Answer -1. Based on training and equipment 2. Risk -benefit analysis (risk a lot to save a lot, risk a little to save a little) Describe the response options available for Exposure protection/Isolating the Area - Correct Answer -1.Establish initial isolation zone 2.Establish protective action distance 3. Establish control zones Describe the response options available for Defensive Control Techniques - Correct Answer -1. Damming (Overflow or Underflow) 2. Diking 3. Retention 4. Dispersion 5. Absorption 6. Adsorption 7. Dilution 8. Dissolution 9. Diversion 10. Vapor dispersion 11. Vapor suppression 12. Ventilation 13. Remote valve shutoff What is Damming... - Correct Answer -Physical method of confinement by which barriers are constructed to prevent or reduce the quantity of liquid flowing into the environment. Consists of constructing a barrier across a waterway to stop/control the product flow and pick up liqu id or solid contaminants What is Underflow Damming ... - Correct Answer -Spill control tactic used to trap floating lighter than water materials behind the dam. Dam is constructed in a manner that allows uncontaminated water to flow unobstructed under the dam while keeping the contaminant behind the dam. What is Overflow Damming... - Correct Answer -Spill control tactic used to trap sinking heavier than water materials behind the dam. With the product trapped, uncontaminated water is allowed to flow unobstructed over the top of the dam. What is Diking... - Correct Answer -Physical method of confinement by which barriers are constructed on ground used to control the movement of liquids, sludges, solids, or other materials. Prevents the passage of hazmat from entering an area where it will produce more harm. What is retention... - Correct Answer -Physical method of confinement by which a liquid is temporarily contained in an area where it can be absorbed, neutralized, or picked up for proper disposal 3 What is dispersion... - Correct Answer -Chemical method of confinement by which certain chemical and biological agents are used to disperse or break up the material involved in liquid spills on water may result in spreading the hazardous material over a large area. What is absorption... - Correct Answer -Absorption occurs when one material enters the cell structure of another and is retianed within. Absorbents retain the properties of the materials they absorb and must be treated and disposed of as hazardous material What is adsorption... - Correct Answer -Adsorption is different from absorption in that the molecules of the hazardous materials physically adhere to the adsorbent material Adsorbents do not swell like absorbents Produces heat and can cause spontaneous combustion must be disposed of properly. Examples: activated charcoal, silica, aluminum gel, fuller's eath, POROUS clay and other clays What is dilution.. - Correct Answer -Dilution involves applying water to a water soluble material in order to reduce the hazard. It is a useful way to preform decontamination but it is not a practical practical spill control method as it typically requires so much water that it creates a runoff problem What is dissolution... - Correct Answer -Dissolution is the process of dissolving a gas in water. This tactic can only be used on water -soluble gases such as chlorine or anhydrous ammonia. What is Diversion... - Correct Answer -Physical method of confinement by which barriers are constructed on ground or placed in a waterway to intentionally control the movement of a hazmat into an area where it will pose less harm to the community and the environment What is Vapor Dispersion... - Correct Answer -Vapor dispersion is that action taken todirect or influence the course of airborne hazardous material. Pressurized streams (hoselines or unattended master streams) create turbulence which increase the rate of mixing with air and reduces the concentration of the hazardous material What is vapor suppression... - Correct Answer -Vapor suppression is the action taken to reduce the emission of vapors at a hazmat spill. Fire Fighting foams are effective on spills of flammable and combustible liquids. Water -miscible materials such as alcohols, esters and ketones destroy regular firefighting foams and require alcohol -resistant foamsThe benefits of buying summaries with Stuvia:
